1 Claim.

Given the upper and lower structures of a loom temple, the same having coactive parallel means to grip the cloth and one such structure being adapted to be aixed to the frame of the loom,

the object of this invention is to make it possible to effect adjustment of the movable structure toward or from the other structure to vary the grip on the cloth and the securing of the movable structure then in a denite relation to the fixed structure. In the example herein set forth there is means interlocking the two structures and which prevent displacement of the movable structure angularly not only in a horizontal plane but in a vertical plane extending lengthwise of the coactive cloth gripping means.

In the drawing,

Fig. l shows the improved temple in plan, applied to a loom;

Fig. 2 is an underneath plan of the upper member and Fig. 3 a plan of the lower member;

Fig. 4 is a side elevation of thetemple;

Fig. 5 is a section on line 5 5, Fig. 4; and

Fig. 6 shows a fragment of one of the spindles Il 25 The base I, generally oblong in plan, has the upstanding integral block 2 reaching across one end and an upstanding lug 3 centrally located at its other end, the block having an upwardly open groove 4 extending at right angles to the base 30 and, relatively inwardly of the slot, the upwardly open clearance notches 5.

The cover 6, also generally oblong in plan, has an integral block 1 reaching across one end and depending lugs 8 located at its other end so as to straddle and be equidistant from lu'g 3 when the cover is secured on the base, the block having a depending rib 9 extending at right angles to the cover.

When the cover is superimposed on the base rib 40 9 is snugly received in the groove 4, each of which has its sides perpendicular to the general plane of the base `or cover, as the case may be, or parallel to each other.

What expedient is used to mount the revoluble rollers I0 in the support formed by the base and cover is not material, but I prefer to provide the cover and base with xed spindles on which the rollers are journaled. Thus, one such spindle Il is here shown passed through each lug 3, 8, there 50 being holes I 2 in block 2 and rib 9 to receive the entering ends of the spindles, whose outer ends may be formed as screws (Fig. 6) to be screwed into the lugs. The spindles of the cover when the latter is applied to the base enter the clearance notches 5. The rollers are respectively penetrated axially by the spindles and are parallel and equally spaced, and when the upper member, comprising the cover and (here) two rollers, is applied to the lower member, comprising the base and (here) one roller, the top of the lower roller will be above the horizontal plane of the bottoms of the upper rollers so as to maintain a bend in the margin of the cloth a (assumed to be held taut between the take-up and vlet-off instrumentalities of the loom) as indicated in Fig. 5.

The rollers are all free to be rotated by the cloth, the upper rollers then turning reversely to the lower roller. They are here adapted to resist the tendency of the cloth to shift axially of the rollers, that is, away from the ends thereof which adjoin the slo-t-and-rib interlock, by each having a circumferentially ribbed periphery each rib-forming volute I3 of which itself presents a roughened peripheral surface, whereby, without the rollers exerting clamping pressure on the cloth and without their acting to mar it in any way, the rollers nevertheless have an eiective grip thereon. Preferably the ribbed form is the result of helically groovng the rollers, as at I4, and the rib of the lower roller is of one hand and those of the upper rollers of the opposite hand; in the example the cloth travel being toward the observer in Fig. 1 the rib of the lower roller is pitched left-handed and those of the upper rollers right-handed so that the tendency is to feed the 'cloth toward the right or into the slot shown existing between the cover and base in Fig. 3.

I5 is a screw which is tapped into the hole I6 of the base and extends freely through a hole I'I in the cover at the interlocked ends of the base and cover; and tapped into the cover are three set-screws I8 arranged to bear against the base, two being at one side and the third at the opposite side of the transverse line, parallel with the interlock, occupied by screw I 5. According as the screw I5 is adjusted up or down so its head determines the possible displacement of the upper structure (formed by the cover and its cloth-gripping means I) from the lower structure (formed by the base and its cloth-gripping means I). The screws I 8 coact with the head of the screw I5 by contacting with the base or xed structure to maintain the cover or movable structure in a deiinite position once the adjustment has been completed, such definite position being that in which the axes of the means IU of the movable structure remain extending horizontally and also both lying in the same horizontal plane. To conne the movable structure against displacement horizontally in its own plane and to afford means to resist its angular displacement in a vertical plane extending lengthwise of its means l0 the interlock formed by the prescribed groove 4 and rib 9 is provided.

The base has a shank 20 which is held in supporting means 2| (well known in the art) attached to the breast beam 22, as shown in Fig. 1. It will be understood that a complementary temple, related, to its shank relatively reverseiy" to that shown, is active on the cloth at its opposite margin.

Having thus fully described my invention what I claim is:

The hereindescribed loom temple comprising upper and lower structuresfhavi'ng, coactiva, parallel spaced elongated means to grip the clotllandi one structure being adapted to be aixed to a loom frame and having, in endwise oiset relation to said means, an integral projection reaching toward the other structure and the latter structure being movable toward and from the first-named structure, a headed screw freely penetrating and having its head exerting pressure on the movable structure, said screw being tapped into said proj ecton.. and several screws arranged spaced around thewheaxdedf screw andI tapped into one and bearing against the other structure, said projection having a groove and said movable member having a rib snugly fitting the groove, and said nih and groove extending transversely of said meanstand eachiiaving its side faces parallel with each other.,
